2. Two cyclists start biking from a trail's start 3 hours apart. The second cyclist travels at 10 miles per hour and starts 3 hours after the first cyclist who is traveling at 6 miles per hour. How much time will pass before the second cyclist catches up with the first from the time the second cyclist started biking?

Note that we are asked: "How much time will pass before the second cyclist catches up with the first from the time the second cyclist started biking?" So it's better x to be the second cyclist's travel time and x+3 the first one's to get the answer right away.
